BERNARD LEBLANC, or LAC rnonrrnn n, QUEBEC, CANADA.

LOG-HAULING SLED. I

T all whom i may concern:

Be it known that I, BERNARD LEBLANC, a

subject of the King of Great Britain, resid-,

ing at Lac Frontiere, Province of Quebec, Canada, have invented certain new and useful Improvements in Log-Hauling Sleds; and'I do hereby declare thatthe following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same. 7

The present invention pertains to a novel log hauling sled adapted for transporting logs in a forest. I

One of the objects of the invention is the provision of a device of this character hav ing a large surface of contact with the road 7 and so constructed that it does not stick in soft snow. This object is accomplished by constructing the body of the sled in the 30 ber of them may conveniently be assembled in a train. Preferably, the train comprises pairs of sleds, the members of a given pair being rigidly secured to one another, while the pairs themselves are pivotally connected. Each sled is provided with a number of sockets and pivot brackets adapted for attachment to the ends of the bars which connect the pairs of .sleds and the members of the pairs. The sockets and brackets are so disposed that all the sleds of a train may he of the same construction and adapted to cocupy any position in the train.

The invention is fully disclosed in the following description and in the accompanying drawings in which:

. Figure 1 is a side elevation of a train of sleds;

Figure 2 is a plan view of the sleds;

Figure 3 is an end elevation;

Figure 4 is an enlarged detail of Figure 3;

Figure 5 is a section on the line 55 of Figure 2; igures 6 and 7 are perspective views of the connecting rods;

Application filed July 22, 1924., Serial No. 727,538. I

Figure 8 is a section on the line 88 of Figure 2; I

Figure 9 is a section on the line 9-9 of Figure 8; Figure 10 is a detail, partly in section, of the pivot connection between sleds; and,

Figure 11 is aperspective view of one of the side braces.

Reference will now be'had to these views by means of like characters which are employed to designate corresponding parts throughout.

Each sled comprises a metallic body hav ing substantially the shape of a barge. The

body is formed with a relatively narrow and longitudinal flattened bottom 1, from the edges of which extend upwardly sloping portions 2. At the edges of these portions are formed vertical sides 3. The ends of the body are curved upwardly as indicated by the numeral 4 in Figure 9, whereby the barge shape is completed. 7

-' Within the body are placed reinforcing members consisting of channel members 5 riveted to the portions 2 and lying parallel to the bottom 1. Y The bottom is likewise engaged by a pair of reinforcing channels 6 riveted thereto, there being interposed a web 7 to which these members are also riveted. To the outer surface of the bottom portion is secued a runner 8 by means of the rivets which pass through the web 7. The function of the runner is to hold the sled against slipping laterally.

Across the body and on the upper edges of the reinforcing members 5 and 6 is laid a knee 9, better known in the art as a steady bunk. The member '9 is held to the reinforcing members by means of bolts 10 which further support a wearing plate 11. To the 6? sides 3 are riveted longitudinal angle irons 12 to which the bunk is further secured by bolts 13. The forward and rear edges of the body are engaged by-strips 14 having their ends bent as at 15 over the sides3. These members are riveted to the body, and the rivets 16 which pass through the. bent ends 15 also serve to retain socket members 17 Figure 5) at the corners for the purpose pointed out below.

Upon the steady bunk 9 is placed a bolster or swinging bunk 18. This member is also provided at its lower surface with a wearing plate 19 held by screws 20 and resting upon the wearing plate 11. The bunk 18 is held pivoted to the steady bunk 9 by means of a king rod 21 passed through the two memhers-and also through the plates 11 and 19. The lower end of this rod rests on the upper edges .of the central reinforcing channels 6 and the Web 7, as shown in Figure 8.

Side braces 22 are secured to the body sides 3 and have bent ends 23 fixed to the steady bunk 9. One of these braces extends from each corner of the body as may be seen in Figure 2. To each side of-fthe bunk 18 are attached three pivot brackets, each comprising a body 24: and an ear 25. 'The end brackets are placed against the bent ends 23 of the side braces 22 and are supportedby bolts 26 which pass through both these. members.

A train of such sleds is constructed by securing the individual sledsin pairs, the

pairs being pivotally connected toone another, while themembers of each pair are rigidly connected to one another. This assembly is accomplished by securing rods 27 to the rear sockets 17 of the adva ce sled 29'. These rods. are constructed so that they may intersect one another, being provided-with intermediate raised portions 28. The remaining ends are pivoted to the end brack ets on the remaining sled 3,0 of thesame pair. Thus two sleds 29 and 30 areconnect ed in fixed relation to one another. This pair is followed by another pair of, sleds connected in the same manner. ,The two pairs are, however, pivotally connected to one another by means of a pair of rods 31 extending from the 'rea'rsockets 17 ofqthe sled 30 to one of the intermediate brackets 24 of the sled 32 of the following pair. The rods are pivotally connected to the brackets by means of a headed pin 33 passed therethrough and througlrthe ear 25. A cotter pin 34 is passed through the lower end of "the pin 33 in order. to hold the latter, in

place.

The sleds ofa given pa r are so spaced as conveniently to accommodate logs 35 placed across the swinging bunks 18 thereof. Each bunk is formed with apertures 36 at its'ends in which may. be secured the ends of a chain 37 which is passed over the first layer 38 of logs. over the second layer 40, this chain having hooks 41 at its ends for. attachment to the chain 37 near the ends thereof. One or sore layers of logs may thus be individually chained to the immediately lower layer, as shown in Figure 3. In this manner a solid base is formed. The remaining logs may then be piled-in pyramid manner, it being necessary to pass a chain over each third layer forefrainple.

l Vhile a specific embodiment of themvention has been illustrated and described it is to be understood that various alterations in the details of construction may be made without departing from the spirit of the invention as indicated by the appended claims. V v

Having thus fully described the invention,what I claim as new and desire to protect by Letters Patent is 1. A log hauling sled comprisinga body portion, having a relatively narrow longi tudinal bottom, sloping portions extending therefrom, side portions formed at the edges of said sloping portions, a runner secured to saidbottom, and a steady bunk placed across said bottom and resting on the sides thereof. V I 7 2. A log hauling sled comprising a body portion having a relatively narrow longitudinal bottom, sloping portions extending therefrom, side portions formed at the edges of said sloping portions, a runner secured to said bottom, reinforcing members secured within'said body and extending. longitudinally thereof, and "a steady bunk placed across saidbody and securedto said reinforcing members.
